I have an acer laptop, aspire M It came with a pre-installed windows 8.

I've made a boot usb key with ubuntu 13.04, created a 4gb swap partition, and an ext3 partition for ubuntu.

Then on the reboot, it only finds ubuntu in the Grub.

I'm no expert. I know my way around the basic stuff, basic understanding but that's it.

well trying to install Ubuntu after pre-installed windows is not a good idea.. –  Sushantp606 Nov 27 '13 at 1:46
    
@Sushantp606 Surprisingly, Ubuntu now has excellent support for dual-booting. Just be sure you know how to troubleshoot simple errors, and it should work like a charm. –  Dillmo Nov 27 '13 at 1:50

Luckily, this is an easy problem to fix. Here's what you need to do:

  1. Open a Terminal emulator with Ctrl+Alt+T
  2. Type sudo update-grub and hit Enter
  3. Wait for the command to finish running.
  4. Shut down. (Don't restart! You may have to reboot again to get to Windows 8 if you do.)
  5. Turn on your computer.

Now, you should see Windows 8 in the GRUB2 boot menu. Have fun with Ubuntu!

Hello Dillmo! Thanks for your answer. Ubuntu IS a lot of fun! Unfortunately, it didn't seem to work properly. I did the grub update three times, and when I shut down the computer, ubuntu "stalls" on two little beads out of five. Any clues? Thanks! –  Charles Nov 27 '13 at 17:28
